Example Embodiment

[0078] Examples of solvents used in the preparation of flying insect repellent products include lower alcohols such as water, ethanol, and isopropanol; ketone solvents, ester solvents, and hydrocarbon solvents such as n-alkanes or isoalkanes. Examples of surfactants include: polyoxyethylene hydrogenated castor oil, polyoxyethylene higher alkyl ethers (polyoxyethylene lauryl ether, polyoxyethylene oleyl ether, etc.), polyoxyethylene alkylphenyl ethers, polyoxyethylene Nonionic surfactants such as oxyethylene higher fatty acid esters, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene glycerol fatty acid esters, polyoxyethylene polyoxypropylene alkyl ether, etc.; laurylamine oxide, stearamide Advanced alkyl amine oxide surfactants such as oxides, lauramide propyl dimethyl amine oxide, etc. These surfactants may be used alone or in any combination.

Example Embodiment

[0086] [Example 1]

[0087] The flying pest repellent fragrance composition of the present invention was prepared as follows: 8.0% by mass of p-tert-butylcyclohexyl acetate and 3.2% by mass of phenethyl acetate were prepared as the (a) component of the flying pest repellent fragrance ingredients. Acetate compound represented by general formula (I); 14.3% by mass of terpineol, 9.8% by mass of geraniol, and 12.0% by mass of dihydromyrcenol as flying pest repellent fragrance ingredients (b) The ingredients are monoterpene alcohols and / or aromatic alcohols with 10 carbon atoms, 38.0% by mass of dipropylene glycol as the repellent effect sustained component, and 14.7% by mass of other flying pest repellent fragrances (including 7.1% by mass of phenethyl alcohol And 1.6% by mass of cinnamyl formate). The blending ratio of the (a) component to the (b) component in the flying pest repellent fragrance composition was 0.32 times.

Example Embodiment

[0091] Comparing to Example 1, 12 mg of threon acetate was mixed as the component (a) in the flying pest repellent fragrance ingredient, that is, the acetate compound represented by the general formula (I); 28 mg of geraniol was used as the flying pest repellent fragrance ingredient (b) Ingredients, namely monoterpene alcohols and / or aromatic alcohols with 10 carbon atoms, and each repellent effect sustained component is blended into the mixture to prepare flying insect repellent fragrances that can be used in the flying insect repellent product of the present invention combination. With respect to the obtained flying pest repellent fragrance composition, the sustainability evaluation test 1 described below was implemented. In this test, the repellent activity against the adult Culex pipiens (♀) was used as the index of sustainability evaluation.

[0092] After impregnating a 15 cm diameter filter paper with 0.5 mL of an acetone solution containing the above-mentioned flying pes...

Abstract

Provided are a flying-insect pest repellent product having excellent repelling effect on flying insect pests while utilizing characteristics of silicone rubber, and a method for repelling flying insect pests. In the flying-insect pest repellent product of the present invention, obtained by retaining a flying-insect pest repellent fragrance composition containing a flying-insect pest repellent fragrance component on a rubber molded article containing silicone rubber and having a hardness of 50 or less, the rubber molded article is an annular rubber molded article provided with an expandable annular part into which a part of the human body or an object is inserted or fitted, and the flying-insect pest repellent fragrance component is volatilized for 5-15 hours from a surface of the annular rubber molded article in a state in which a part of the human body or an object is inserted or fitted in the annular part.

Description

technical field [0001] The invention relates to a product for repelling flying pests and a method for repelling flying pests. Background technique [0002] Conventionally, a method of applying a repellent containing DEET (N,N-diethyltoluamide) to the skin surface has been widely used against flying pests such as mosquitoes, gnats, midges, and flies. However, since DEET has slightly lower volatility than general fragrance ingredients, it cannot expect a spatial repellent effect. On the other hand, although normal-temperature volatile insecticidal components, such as pyrethroid-based Yibangning, can be volatilized in space to achieve the repelling effect on flying pests, there are many normal-temperature volatile insecticidal components. The use of is to be kept at arm's length. [0003] Therefore, several attempts to use volatile natural essential oils and their constituents as repellent ingredients have been proposed. For example, citronella oil and its main component, ci...
